Solution Overview

Problem

Conventional evaporator cleaners using synthetic disinfectants like OIT have harmful residual effects on the human body and lack effective odor bactericidal ability, leading to odor re-proliferation.

Innovation Solution

A cleaner composition comprising a solvent, surfactant, and natural extracts of sage and eucalyptus, with specific weight percentages, providing synergistic odor bactericidal and air-conditioning odor reduction effects while minimizing human body harm.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If synthetic disinfectants like OIT are used for cleaning, then disinfection performance is improved, but harmful residual effects on the human body occur

Engineering Contradiction:
Improvedisinfection performanceVSAvoidharmful residual effects on human body
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the chemical composition parameters by replacing synthetic disinfectants (OIT) with natural extracts (sage and eucalyptus) at specific concentrations (0.1-2.0% sage extract, 0.1-2.0% eucalyptus extract). This parameter change maintains disinfection effectiveness while eliminating harmful residuals, directly resolving the contradiction between disinfection performance and human safety

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite cleaning composition combining multiple natural extracts (sage, eucalyptus, tea tree, rosemary) with surfactants and solvents. This composite approach synergistically enhances disinfection performance while using naturally derived components that are safe for humans, simultaneously addressing both disinfection effectiveness and reduced harm

Inventive Principle:
Principle #40Composite materials

2Productivity

If general cleaning agents are used for cleaning, then cleaning ability is provided, but odor bactericidal ability is insufficient leading to odor re-proliferation

Engineering Contradiction:
Improvecleaning abilityVSAvoidodor bactericidal ability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent merges cleaning functions with odor bactericidal functions by combining surfactants (for cleaning) with specific natural extracts containing antimicrobial compounds (sage, eucalyptus, tea tree, rosemary). This functional merging ensures both cleaning ability and sustained odor prevention through the synergistic action of multiple extract components

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent ensures continuous odor prevention by using natural extracts that provide sustained antimicrobial activity after cleaning. The extracts continue to inhibit odor bacteria proliferation post-cleaning, providing ongoing protection rather than temporary effect, thus maintaining reliable odor control over time

Inventive Principle:
Principle #20Continuity of useful action

AI summary

A cleaner composition has a solvent, a surfactant, a natural extract, and an additive. The cleaner composition has excellent antibacterial properties by using a natural extract including small amounts of a sage extract, a eucalyptus extract, or a combination thereof of the sage extract and the eucalyptus extract. The cleaner composition has an odor bactericidal capability of 99% or more. The cleaner composition has an air-conditioning odor reduction effect and has low harmfulness against the human body.
